First pic is either a ric or a hairy mushroom. If you just got them in then the mouth (and possibly the tentacles) may be a result of shipping/acclimation stress. If lighting and flow are right they should settle in and show their true morphology.
Second pic I can't see the jelly substance well enough to be able to help with an ID but my best guess is a sponge of some sort. The trumpet things look like recently moves mushrooms but thats also tough to tell from the picture.
